This is the depth gage graph of 2.5 hours of water variations due to the seiche from the July 2016 storm that resulted in many inches of rain and the destruction of Saxon Harbor Marina. The “4.9 ft.” in the top left corner is the current depth. The water went up and down almost 2 feet every 30 or so minutes.

This graph during normal weather showing a tighter up and down seiche of less then 6 inches.

Nobody expects to see a Spanish Galleon... Especially 25 miles off of Outer Island in Lake Superior. El Galeon Andalucia heading to the Soo after the Duluth Tall Ships. Our paths crossed while we were returning from Isle Royal.
